Furnace should have an on off switch near it. Turn it off. Turn wall thermostat off.
Air filter screens are flat and wide. Typically they slide into the side of your furnace. Some slide in the inside at the large opening where the air flows, and some slide on the outside. Take a flash light and look for a long slot where the unit's filter would slide in. Pull the old one out if it has one.
Inspect it. If it is dirty replace it with the correct fit for your unit. If the furnace is hardly ever used, then it should appear clean. New filters trap dirt, dust, or allergens. Pick one that suits your need. If the unit is not used for a while, then of course, it may be clean. Replace as needed.
Some homes have large ceiling or wall vents with filters behind them. Normally, you will see tabs for opening the grille to install a filter.
A dirty filter will stop air from being blown. A filter is needed to keep dust and dirt out of critical areas of your equipment. Saving you hundreds of dollars in replacement or repair of the unit.
Hope this helps!
